NITRI) STATES FRIEDRICH HEINRICH FLOTTMANN, OF BOCHUM, GERMANY.

VACUUM-PAN.

SPECIFICATION forming part of Letters Patent No. 447,673, dated March 3,1891. Application filed October 28, 1890. Serial No. 369.566. (Nomodel.) Patented in Belgium August 13, 1890, No. 91,629.

to facilitate the manipulations which have to be carried out. with theapparatus and to render it adapted for different purposes besides thosementioned.

In the annexed drawings an apparatus carried out according` tomyinvention is shown by Figures 1 and 2 in sectional elevation in twodifferent positions, Fig. 1 representing the position in which theapparatus is charged and emptied and Fig. 2 the working position. Fig. 3is a central transverse section corresponding toFig. 2.

The apparatus is composed of two vessels A and B, inserted one withinthe other. The outer vessel A has two trunnions 1 2, with which it ismounted in the respective bearings 3 4, and it'is provided with thestuffingboXes 11 12, arranged at a right angle to the axis of thetrunnions 1 2. These stuffingboXes serve as bearings for the trunnions 56, with which the inner' vessel B is furnished. The trunnion 2 of thevesselA is hollow, and to the same is connected by means of astuffing-box a pipe 9, serving for the supply of steam, hot or coldwater or air, or compressed air, or through which air is exhausted frombetween the vessels A and B. The trunnion 1 is shown as being hollowalso, in View of allowing the same to be utilized for any attachment-s;but as represented it is closed by a cover. The trunnions 5 6 of vthevessel B are both hollow. The trunnion 5 is provided with a screw-plug18 for allowing it to be opened and closed, while the trunnion G isclosed by a cap D, formed in one piece with the cover of thestuffing-box 12, and being in consequence stationary relatively to thevessel A, whereas the trunnion 6 rotates therein. The said cap isprovided with a tubular branch piece 13, to which is attached a cock Hwith flexible pipe 14, leading to an airpump or other exhauster (notshown in the drawings) and a vacuum-gage G. Moreover, the cap is fittedwith a cock E and a tube F, closed at the bottom and adapted to containa thermometer.

C is a perforated partition-plate or false 6o bottom, and 15 1G aredoors.

For turning the outer vessel A,together with the inner one B,'from thecharging and dis-v charging position, Fig. 1, into the Working position,Fig. 2, or vice versa, the trunnion 1 65 brought about withoutdisturbance of its con- 7o nection with the exhauster on account of theflexibility of the pipe 14.. The rotation of the inner vessel B withinthe outer one is produced by a spur-wheel Z, keyed on the end of thetrunnion 5, the said spur-wheel being con- 7 5 nected When the apparatusis in working position with any suitable driving-gear. (Not shown in thedrawings.)

If the apparatus is to be used, it is brought into the vertical orcharging position, Fig. 1. 8o

The cocks E and H are closed, the screw-plug 18 is removed, a funnel 19is put in its place, and the substance to be treated is introducedthrough the same into the vessel B, the substance, if solid, dropping onthe perforated plate C. The funnel is then withdrawn again, the plug V18is reinserted, the apparatus is turned into its horizontal or workingposition, Fig. 2, cock H is opened and communication thereby establishedbetween the exhauster 9o and the vessel B, the heating, cooling, orother medium is introduced through pipe 9 into the space between thevessels A and B, and the vessel B is put in rotation by means of thespur-wheel Z and its driving mechanism.

Vhen the operation is finished,the apparatus is brought back to thevertical position,cock H having previously been closed. Any liquidcontained in the vessel B may then be drawn off by the cock E. Solidmaterials are disroo charged either through the trunnion 5 or throughthe apertures closed during the eperation by the doors l5 1G. doors haveto be removed, the pipe 9 is first Whenever these closed by means otvalve IO and the cock I is opened, while the apparatus is in horizontalposition for allowing the medium contained in vessel A or water ofcondensation to issue;

but with exception of this case the vessel B may be charged anddischarged, and samples may be taken therefrom Without eduction of theheating or cooling medium from the vessel A.-

The apparatus may be employed in brewcries and distilleries foi-boiling`and cooling mash and wort, in sugar nianufactories for extracting thejuice from beet-root slices, in the coneentrationof solutions ofvariouskinds, in the desiccation of meat, malt, refuse matter formanure, and other materials. Besides it is serviceable for thedisintegration of bones while being,` subjected to heat, and, providedthe walls of the vessel B are perforated and the cover of the hollowtrunnion l is removed, it may also be used as lnalting apparatus.

I claim as my invention l l. The combination of the outer vessel A,

having the hollow trunnion l and the trunnion 2, and stuffing-boxes lll2, arranged at a right angle to the said trnnnions, bearings 3 -l forreceiving` the trunnions l an inner vessel B, having` hollow trunnions 5(i, with which it is mounted in the stuiing-boxes Il l2, pipes inconnection with the trunnions 2 and G, and means for rotating the VesselA in its bearings 3 4E and the vessel B in the stufiing-boxes 1ll2,substantially as described.

2. The combination ot the outer vessel A, having the hollow trunnion land the trunnion 3, and stuffing-boxes l1 12, arranged at a right angleto the said trunnions, bearings 3 l for receivingl the trunnions l 2, aninner vessel l, having hollow trunnions 5 6, with which it is mount-edin the stuffing-boxes 1l 2, pipe 9 in connection with the hollowtrunnion 2, the closed stuIiing-box cap D on trunnion G, pipe 13,attached to the said cap, and means for rotating the vessel A in itsbearings i and the vess'el B in the stniiing-boxes 1l l2, substantiallyasvdescribed.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
